High-Density Blade Server

The Dell EMC PowerEdge M640 is a half-height blade server built for dense data-centre deployments. It carries two Intel Xeon Gold 6230 processors, each running at 2.1 GHz with 20 cores and a 3.9 GHz turbo frequency. The system ships with 512 GB of DDR4 2666 MHz registered ECC memory across 16 slots, leaving room to grow to 1.5 TB. It targets organisations running virtualization, private cloud or high-performance computing workloads.

Storage Controller and Network Daughter Card

A Dell PERC H330 controller provides 12 Gb/s SAS and SATA connectivity with RAID 0, 1, 5, 10 and 50 support. Two 1.92 TB SAS SSDs are pre-installed in the dual 2.5-inch drive bays. The Broadcom 57810S-K dual-port 10 Gb blade network daughter card adds high-speed fabric connectivity without consuming a mezzanine slot. iDRAC9 Enterprise enables full remote management and automation from deployment through retirement.

Chassis Integration and Daily Operations

The blade fits PowerEdge MX and M1000e chassis, so power, cooling and networking are shared at the enclosure level. No front bezel or ready rails are included, which is standard for blade form factors. Matrox G200 graphics with 8 MB video memory handles basic console output. Buyers needing direct-attached NVMe storage or additional mezzanine cards should verify chassis slot availability before ordering.

Questions about this item

When will the DDR4 memory modules need replacement or upgrade?

The server holds 512 GB across 16 slots at 2666 MHz; maximum capacity is 2 TB, so you can add modules later without removing the existing 32 GB sticks.

What limits sustained compute throughput first?

Two Xeon Gold 6230 CPUs provide 40 cores at 2.1 GHz with 3.9 GHz turbo; the 20-core per socket ceiling is the hard compute limit.

How much heat and power does the blade produce under continuous load?

As a half-height blade it draws cooling and power from the M1000e or MX chassis; the dual 20-core CPUs and 512 GB DDR4 set the thermal envelope the chassis must handle.
